When starting up my iMac G4 running Mac OS 10.4 all that appears is a blue screen.  The cursor appears but the dock and toolbar ar not visible.  I have reset the PRAM (command, option, P,R).  Any suggestions on how to get my G4 to startup?

    "Try Disk Utility


    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

    3. Click the First Aid tab.

    4. Select your Mac OS X volume.

    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."




    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.


    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)


    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
